This part is qualified to AEC-Q100, the automotive stress qualification standard. If your BOM calls for AEC-Q100 traceability, the STM8AL3188TAY delivers it; if the program requires PPAP documentation, confirm with your quality team that the supplier can provide the cert package. ## 16 MHz core and memory — sizing the firmware The 16 MHz STM8 core with 64 KB Flash, 4 KB RAM, and 2 KB EEPROM is sized for automotive body-control nodes — LIN slave modules, window lift controllers, seat position sensors. The 2 KB EEPROM (separate from Flash) stores calibration and fault codes without wear-leveling overhead. ## Package and supply — board-fit notes","metaTitle":"STM8AL3188TAY 8-bit MCU, 16 MHz, 64 KB Flash, AEC-Q100, NRND","metaDescription":"STMicroelectronics STM8AL3188TAY automotive 8-bit MCU, 16 MHz core, 64 KB Flash, 4 KB RAM, 2 KB EEPROM, AEC-Q100 qualified.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"STMicroelectronics","Speed":"16MHz","Series":"Automotive, AEC-Q100, STM8A","Package":"Tray","RAM Size":"4K x 8","Core Size":"8-Bit","EEPROM Size":"2K x 8","Peripherals":"Brown-out Detect/Reset, DMA, POR, PWM, WDT","Connectivity":"I²C, IrDA, LINbus, SPI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"41","Core Processor":"STM8","Package / Case":"48-LQFP","Product Status":"Not For New Designs","Data Converters":"A/D 25x12b; D/A 2x12b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"STM8","Program Memory Size":"64KB (64K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C ~ 85°C (TA)","Supplier Device Package":"48-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"1.65V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.3496","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/0093a44ad742d68422bcf71762e1079a.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STM8AL3188TAY/alternatives.json"},"ai":{"faq":[{"question":"Is STM8AL3188TAY obsolete or NRND?","answer":"It is not yet fully discontinued, but STMicroelectronics advises against starting new designs with this part.
